If someone you love (even you, maybe) has a health condition, specific allergies or implants, emergency medics need information. You should probably also carry a flash drive that contains everything they need to know in your wallet or purse. (Someone else will have to help you with that). But if your wallet isn't available, then a vintage bracelet at least serves as something of a warning.

It is important medical history, right there on your wrist, perhaps with emergency phone number, email, or website details on the back.

Prices start at $49.00, and don't go all that much higher. All depends upon the price for engraving the bracelet.
